Do you know how to compute the vertical shift for font drawing ?
Explaination: I am drawing 2D letters in a 3D world and I would like to return to a newline. So I need to compute the vector between the origin point of the 1rst baseline and the new origin point of the 2nd newline.
I think this operation should keep in mind the YBearing, the height of the letter and real size of the plan which will draw the font texture.
It appears it would be computed as :
baseline-to-baseline-shift = ascent - descent + linegap (descent is a negative value)
These parameters should be globals, so now the problem is just to find accessor to it.
